Big part are, but ofc there are many of us that arent (im not tho, i love bg, gl and bl as equal), is easy to spot them bc some are mysoginistic AFFFF, hate women so much they call the only woman in the story a hoe even if she hasnt even talked to the mc(some of them are not mysoginistic but im not goin to get on detail).
And the part that isnt are those who find bl tropes more appealing, like handsome men and many other reasons. I actually dont care if their fetish is gay man, people have weirder fetishes than that.

are fujoshis fetishist?
